View official documentation
Purpose:
Floating-point Add (vector). This instruction adds corresponding vector elements in the two source SIMD&FP registers, writes the result into a vector, and writes the vector to the destination SIMD&FP register. All the values in this instruction are floating-point values.
Result:
poly64x1_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
poly64x1_t a = {
1ULL, 2ULL
};
poly64x1_t b = {
3ULL, 4ULL
};
poly64x1_t result = vadd_p64(a, b);
uint64_t* res = (uint64_t*)&result;
for (int i = 0; i < 2; ++i) {
printf("%llu ", res[i]);
}
printf("\n");
return 0;
}Prototypes
Assembly Instruction:
EOR
Usage:
poly64x1_t result =
vadd_p64(
poly64x1_t a, poly64x1_t b
)
